ISCO International to Showcase New RF Solutions at CTIA Wireless 2007

ELK GROVE VILLAGE, IL -- (MARKET WIRE) -- March 23, 2007 -- ISCO International, Inc. (AMEX: ISO),
a leading supplier of RF-conditioning and interference-control solutions
for the wireless telecommunications industry, will showcase its products at
booth number 3906 at CTIA Wireless 2007 at the Orange County Convention
Center in Orlando, FL. The exhibit will run from March 27-29.

ISCO will feature a variety of new products and new product applications at
the event, including showcasing its digital Adaptive Notch Filter platform
(dANF) and full line of wireless coverage and capacity enhancing solutions
(such as its Ground Mounted Amplifier, or GMA) for Cellular, UMTS 850/900,
AWS and PCS spectrum.

The dANF will be featured in the CTIA Wireless "Emerging Technology Awards"
display area at CTIA Wireless 2007. The Emerging Technology Awards area
displays the most innovative products and applications in wireless today.
ISCO will also host a press conference on Wednesday March 28 from 1:00 -
1:45 in press conference room 312A - West Hall, 3rd Flr.

The ISCO dANF employs adaptive interference identification techniques to
mitigate the effects of capacity-robbing dynamic interference in wireless
networks. The dANF is an innovative and cost-effective solution for
interference mitigation in wireless systems worldwide. The recent expansion
of CDMA and UMTS technologies into the AWS and 850/900 MHz spectrum poses
unique interference challenges. The ISCO dANF applies adaptive interference
mitigation techniques to help deploy these technologies with greater
flexibility and minimal spectrum loss related to inherently restrictive
design rules that must be managed.

"The unique capabilities of ISCO's Adaptive Interference Management
platform allow us to bring innovative solutions that minimize, even
eliminate, traditional guard-band and transition zone requirements for
mixed mode deployments," said Neal Campbell, Executive Vice President, Next
Generation Products. "The end result is accelerated deployment,
minimizing the sacrifice of valuable spectrum, and maximizing the ability
for disparate technologies to co-exist. This is fast becoming a
requirement, not an option."

Interference

Interference in cellular networks can take on a variety of forms.
Intra-system interference (including self induced inter-modulation), caused
by
co-location with other carriers and technologies, often creates challenging
operating environments. Cross border transmissions from traffic on a
competing carrier's network, spurious emissions from FM, terrestrial
microwave and corporate data links are other typical sources of dynamic,
time varying interference. These types of environments require adaptive
interference mitigation techniques. One of the most ubiquitous varieties
results from re-mining existing 2G spectrum with 3G technologies.

dANF Technology Overview

The digital Adaptive Notch Filter™ (dANF) identifies, prioritizes and
suppresses multiple random and dynamic interference signals that are within
the receive bands of mobile communication systems. These in-band
interference signals are especially prevalent in spread-spectrum
(CDMA/UMTS/WiFi) mobile systems, and are extremely difficult to control
using conventional means. ISCO's new Linux and DSP-based product platform
has improved cost, performance, and time-to-market advantages over existing
solutions, especially in anticipation of the increased system demands
brought about by 2.5G and 3G cellular architectures. This adaptive
interference management (AIM) platform provides the foundation for future
applications of software-based filtering in WiMax, and other 4th Generation
wireless systems.

The dANF technology is compatible with all spread spectrum-based wireless
technologies (CDMA, UMTS, WiFi). The product integrates seamlessly with all
wireless infrastructure manufacturers' cell site equipment. Importantly,
due to the flexible Linux architecture, it is possible to future proof your
network from new types and modes of interference as new wireless
technologies are introduced.
